Effect of Berenuk Fruit Extract (Crescentia cujete L.) on Mortality of Plutella xylostella on Mustard Plants

Quagga
Mustard production in Indonesia in 2022 decreased by 2.9% from the previous year, caused by the Plutella xylostella attack. Efforts to control P. xylostella usually uses synthetic pesticides but harms the environment, so other alternatives are needed ...

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

The roles of olfaction and vision in host-plant finding by the diamondback moth, Plutella xylostella

, 2006
The relative roles of olfaction and vision in the crepuscular host-finding process of a major lepidopteran pest of cruciferous crops, the diamondback moth Plutella xylostella are investigated in a series of laboratory and semi-field experiments.

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Nap1 is essential for eupyrene spermatogenesis and migration in Plutella xylostella [PDF]

Insect Biochemistry and Molecular Biology
Spermatogenesis is a key process for the sexual reproduction species. In lepidopteran insects, spermatogenesis produces two different types of sperms, in which eupyrene sperm carry genomic DNA and fertilize eggs, whereas apyrene sperm are necessary for eupyrene sperm to enter eggs.

Synthesis and Bioactivities of Novel Pyrazole Oxime Derivatives Containing a 5-Trifluoromethylpyridyl Moiety

Molecules, 2016
In this study, in order to find novel biologically active pyrazole oxime compounds, a series of pyrazole oxime derivatives containing a 5-trifluoromethylpyridyl moiety were synthesized. Preliminary bioassays indicated that most title compounds were found

Variation among 532 genomes unveils the origin and evolutionary history of a global insect herbivore

Nature Communications, 2020
The diamondback moth, Plutella xylostella is a cosmopolitan agricultural pest. By analyzing 532 genomes from 114 populations around the world, the authors find evidence supporting a South American origin of this moth, and look for signatures of positive ...

A single transcription factor facilitates an insect host combating Bacillus thuringiensis infection while maintaining fitness

Nature Communications, 2022
Plutella xylostella endures Bt toxins with no performance costs. This study reveals how, depending on the presence of the toxin, this insect modifies MAPK phosphorylation to modulate the transcription factor FTZ-F1 binding, to up- or down- regulate Bt ...

Intraspecific and Interstage Similarities in Host-Plant Preference in the Diamondback Moth (Lepidoptera: Plutellidae)

Horticulturae, 2022
The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is an important insect pest of cruciferous crops. Understanding its preference patterns can lead to more efficient management methods, such as trap crops.
